To keep the momentum leading up tomorrow's release of the full Wolverine trailer, Twentieth Century Fox and star Hugh Jackman have released another brief sizzle reel of The Wolverine footage and it offers another epic tease.

With just six seconds of action-packed footage, featuring shots of most of the key characters, a cameo appearance by Jean Grey (Famke Janssen) and sword-fighting, The Wolverine earned itself a lot of positive buzz yesterday, enough to make up for some of the criticisms generated by the oddly fan-made-looking poster the day prior.

Today, Hugh Jackman and MTV have a slightly extended teaser for The Wolverine and this one hits on the main them of the film: immortality. Beginning with the attack on Logan out in public while sporting his black suit, we then see Yukio and Logan in action, while a voiceover by Logan explains that his mutant abilities and the weapon X procedure that turned him into an Adamantium-laced weapon "can't be undone." That wouldn't mean much on its own if it weren't for the cliffhanger ending of another character telling Logan, "don't be so sure."

Have we just discovered the reason Logan heads to Japan? Will Wolverine finally be able to do something about his immortality by giving up his powers and/or his Adamantium skeleton? Or is it something else entirely?

During production on set in the fall, Jackman and director James Mangold participated in a live chat with Marvel.com where they hinted that the villains of The Wolverine will find a way to get through to Logan and make him vulnerable in ways we've not seen before. Could the labs we find Logan and this mysterious other character have something to do with that?

The Wolverine is directed by James Mangold off of Mark Bomback and Christopher McQuarrie’s screenplay. It stars Hugh Jackman, Svetlana Khodchenkova, Will Yun Lee, Brian Tee, Hiroyuki Sanada, and Rila Fukushima.

The Wolverine hits theaters July 26, 2013. X-Men: Days of Future Past hits theaters on July 18th, 2014.
